Shameless plug time: I'm currently doing a series of cartoons for the Artyfacts section of the Children's BBC website. They are used to illustrate the lives of artists. So far I've done the Spanish painter Joan Miro and Martin Creed, who got the media in a froth when he won the Turner Prize by turning the lights on and off a lot.
For joke cartoons, humorous illustration, caricatures, comic strips and live cartooning/visualisation
